Abstract
A kind of velocity of control system which is based on the single chip microcomputer is introduced in this paper. The system is completed by software and hardware. The hardware is composed of the minimal system of single chip microcomputer and the digital follow-up system .The system includes sample of velocity circuit, A/D transducer circuit, the PWM power amplification circuit, and so on. The software includes the sampling and filtering procedure , scale converseing procedure, displaying procedure, keyboard interrupting procedure, and PID controlling procedure. The system has realized the function of velocity sampling, displaying, alarming and controlling. Also the velocity and related PID data can be setting by key to realize the measurement and control of velocity.
Key words: Single chip microcomputer Electrical engineering Velocity measurement PID control
